There is considerable interest in improving the digestibility of forages and feeds by rumi-
nants. Lignin, the main non-carbohydrate component of the plant cell wall, is a major fac-
tor which affects plant digestibility. the problem has been in not being able to accurately
describe the plant cell wall so as to determine how lignin (or any other component) affects
digestibility. If a more definitive and accurate method was developed, improvements in feed and forage digestibility might be realized. The currently accepted method of fiber
analysis uses gravimetric techniques with detergent extraction. Although it is a relatively
quick and easy proc edure, it is prone to many problems. It has been reproted that hemi-
cellulose can be either over etimated or under-estimated by this method. Other problems
involve the interference of starch, lack of an accurate assay for lignin, poor reproducibility
with some substrates, and filtration difficulties. The objective of this study was to evaluate
a new method of analysis for determining the fiber components of forages and feeds.
